Experimenting with the job system is completely optional imo.
It is, my point being that not knowing what jobs you will get at each shrine and enjoying the system as much as pretty much everyone does, what would be the point of not experimenting with such? The whole point of FFV is the flexibility of the job system and as such almost anyone who plays it will end up grinding atleast a bit to master some of them.
The game does have difficulty spikes, but so do most games. The solution is not necessarily to grind exp or JP, but to figure out what you are doing wrong.
If you are a veteran jrpg player and enjoy challenge as much as i do, sure
But i will say this: I know every ich of final fantasy 9 for example to know that the very optimal strat to get the best of your end game stats are to play the whole game low level, after you unlocked some of the abilities that boost your stats up at each level, then you start to level up
This will mean everybody will do it? No. People will get scaried to do such things and to risk themselves specially going throught an old game completely blind, thats the same for going low level for SaGa endgame bossfights or whatever jrpg you could use as an example.
Most of the people who play those kinds of games for the first time will end up grinding instead of let themselves be challenged, avoiding frustration or failure as much as they can and you can confirm that by searching for some blind playtroughts or streams of this game by yourself.
The encounter rate can be high for sure, but you can always run away from annoying battles very easily. I didn't love every hour of FF5, but I don't think it wasted my time. I enjoyed most of my time with it.
Don't get me wrong, i love the hell out of ffv
But my point wasnt that the game was bad, but that you definitively will end up wasting more time than in CT, CT is a short game
Has no random encounters, specially not nearly as much fights than in FFV and its piss easy to the point you never need to grind or whatever
So, i cant really see any reason why anybody would think its pacing is faster.
